Heated Microplate Sealers

Heated microplate sealers apply controlled heat and pressure to bond film or foil seals across the rim of standard microplates, creating an airtight barrier that prevents evaporation, contamination, and sample degradation during storage, incubation, and transport. These instruments are standard equipment in PCR, ELISA, cell culture, compound storage, colorimetric, and fluorescence assay workflows where unsealed plates introduce variability or cross-contamination risk.

Two main configurations cover the range of laboratory throughput requirements. Manual thermal sealers use an ergonomic lever mechanism to press a heated platen onto the plate surface. The Vitl MicroTS operates at a fixed 170°C ± 2°C, reaches sealing temperature in under 10 minutes, and fits a 220 × 250 × 230mm footprint weighing 4kg — suited for low-throughput benchtop use. Semi-automated models such as the Labnet AccuSeal motorize the drawer and platen, automatically adjusting to plate height and applying uniform pressure. Temperature sets in 1°C increments and sealing time in 0.1-second steps for repeatable results across different plate and seal combinations. Variable temperature models cover a range of 80°C to 200°C, accommodating peelable, pierceable, and permanent heat seal foils and films in thicknesses from 20µm to 105µm.

Furthermore, fully automated sealers such as the Agilent PlateLoc integrate with robotic liquid handling systems via RS-232 serial port and ActiveX control — handling deep-well, assay, PCR, and compound storage plates in high-throughput drug discovery and genomics workflows without operator intervention between cycles.

These instruments apply to Pakistan’s hospital molecular diagnostic laboratories, university genetics research departments, pharmaceutical quality control facilities, and forensic DNA laboratories in Lahore, Karachi, and Islamabad requiring consistent, contamination-free microplate sealing across high-volume sample processing workflows.

Tactical Supply Pakistan supplies heated microplate sealers for PCR, ELISA, genomics, and laboratory sample storage procurement across Pakistan.
